Prof. Eli Ben-Sasson of the Technion's Faculty of Computer Science
and Hanan Steinhardt discussed the various aspects and challenges that digital
coins pose. "The main problem today is how to increase the transaction rate of
about 10 per second to thousands or tens of thousands of transactions per second
... Another challenge is whether it is possible to reach a consensus in a
decentralized manner without burning the planet because the consumption of
crypto energy is increasing at an unsustainable rate. Also challenged by
traditional regulatory forces - has the question of sustainable decentralization
over time. "
